If we wanted to communicate with a civilization on a distant planet, which part of the spectrum would allow us to send messages with the least delay?
  • A: The high frequency signals, like x-rays, would get there faster.
  • B: The long wavelength signals, like radio waves, would get there faster.
  • C: Wait! The speed of the wave will depend only on the amplitude, or strength, of the signal.
  • D: Wait! The speed of all waves on the EM spectrum travel at an identical speed!
